Cuba is working towards creation of a vaccine which is effective against dengue. The country is developing a number of vaccines which are in the pre clinical trial phase and if it turns out to be success then clinical trials would be conducted on human beings. We must take care of the fact that up till now no vaccine has been developed for treating this vaccine which is of endemic nature in a number of tropical countries. All this was revealed at the final session of the Biotechnology convention which was held in Cuba and already we have seen that a number of countries in Asia had been plagued by dengue which is caused due to mosquitoes. Hopefully Cuba will become the first country to emerge with a dengue vaccine and this all is certainly possible as Cuba is considered as a biotechnology powerhouse.
